The problem with the original 5 quart system is similar to the original 5 quart FE pan. You are going to pump the pan dry at high rpm.
That would not be a good thing to do.
Agreed, but just in case someone says "well I have a rev limiter" so it's okay, it's not only high rpm. High cornering 'G force' IMO is more prevalent and as example my GT5 had a high capacity 9 quart pan on it when I purchased it. At the Fun Rally first time on track I was losing oil pressure in some of the corners, thus even on a 9 quart pan oil was walking up the sidewalls of the pan under high g force. I removed the oil pan when I got home to discover it was simply a high capacity and had no baffles to prevent oil moving away from the pickup. I since installed a baffled Aviaid pan as preventing the pickup running dry is more important than pure volume.

It is a combination of the two. Driving conditions and cornering g-forces have just changed since 1972 substantially. The requirements have been upgraded.
Frankly though the Pantera if used even close to it's capability really could benefit from a dry sump system.
At that point it is at a factory GT car like a GT40. The "40" has more available space for the tanks and the 289 works better with the firewall/bulkhead.
When Carroll Smith "determined" that the Pantera won't make a race car, things like that is what he was referring to.
The problem is where to put everything for the dry sump system though.
Just the tank alone is an issue. Probably where the GT4 cars "auxiliary" fuel tank was would work with a tank molded into that cavity.
The engine compartment generally does not lend itself well to the necessary add-ons.
One thing additional that the Chevy wet pans have that the Fords don't are the swing pick up.
I think I recall one of the pan companies Bruce Jodar of the original Cobra Club contracted with to build a 427 Cobra pan was to incorporated the swing pick up?
Long time ago already. I don't remember the exact details now, just the generalities.
